ALBERT OSTRANDER, OF NEXV YORK, N. Y.

GAS-BURNER.

To all whom it may concern:

Be it known that I, ALBERT OSTRANDER, of the City, County, and State 'of New York, have invented a certain new and useful Article of Manufacture, which I have designated The Indestructible Mineral Gas- Burner; and I do hereby declare the following to be a full description of the same.

The object of my invention is to make an indestructible gas burner, free from the corrosive effects of the impurities of gases, and at the same time of a cheaper material than metal. It is well known that illuminating or carbureted hydrogen gases contain always a small trace of Sulfur in it. This when ignited in contact with metal readily combines with it, and thereby causes the vents of the burner to enlar e Or burn out 77 in a very short time. The effects of this imperceptible enlargement of the vents of the burners are manifold, among which may be mentioned Consumption of a greater quantity of gas than necessary for illuminating the room, and as a consequence compelling the consumer to pay large gas bills; and secondly vitiating the atmosphere of the room, besides generating an insufi'erable amount of heat by the increased amount of fiame generated in consequence of the en larged vents, allowing so large an amount of gas to escape. And secondly, another object had in view when making my invention was that of making a cheaper gas burner than could be made from metal, and at the same time a more ornamental burner, from the fact that by the combination of metallic oXids, with the composition of the burner, when miXing, it may be made of various Colors, and thereby produce a burner combining the ornamental as well as the economical and useful.

The nature of my invention consists in the production of a new and useful article of manufacture, to be known and designated in the arts as the mineral gas-burner, Or indestructible mineral gas-burner. But to describe my invention and the method of producing my new article of manufacture I will refer to the accompanying drawings forming a part of this specification, the same letters of reference wherever they occur referring to like parts.

Figure 1, represents a side elevation of the burner, and metallic socket; Fig. 2, a

out section of same parts eXhibiting the conically shaped vents for the escape of the gas.

Letter a, represents the metallic socket, in the upper end of which is cemented the burner b. This burner is made from the fol' lowing mineral substances: feldspar, finely powdered, 20 parts by wt.; quartz, finely powdered, 6 parts by wt.; asbestos, finely powdered, 4 parts by wt. These materials are thoroughly worked into a paste, by the addition of gum or starch water, and if desired to be colored burners, metallic oXids are added to the mass. It will be obvious that these precise proportions may be slightly varied without materially changing the quality of the burner. But as an essential condition of the burner consists in its capacity to resist the action of heat, to prevent cracking or breaking it is believed that no change can be made in the proportion of asbestos used. Ordinary porcelain submitted to the heat incident to the use of a gasburner would not bear the action of it. It will be perceived therefore that my gasburner is not a porcelain, but is made from a composition of materials eXpresSly adapted to the specific duty required of it, that is, its capacity to resist the eXpansive and contractile efl ects of various degrees of heat.

Letter C, is the vent of the burner, and (l, CZ, are two channels or passageways through the head of the burner at an angle of about 80 degrees, and terminating in the main vent. These passageways or channels CZ, (Z, are made of aconical form, and contracting so as to be nearly one half smaller at their termination to form the vent G. The object of this conical form of the channels (l, CZ, is to cause the gas to rush out of the vent with greater force, than if the channels were of equal diameter throughout their length as they are at their apeX. This conical conformation of the channels is a pecularity exclusively pertaining to my indestructible mineral gas burner. In metallic gas burners these channels are made by the use of a drill, and as a matter of course throughout their length of uniform bore. As my mineral gas burners are molded in a plastic state, the channels are formed by means of conical pins inserted through the sides of the burner, in the direction of the dotted outline e, e, (Fig. 2,) and when withdrawn the openings through the sides of the burner plugged up by the composition, and

thus leaving the channels through the head of it conical in form.

When the burner has been molded it is submitted to a partial heat in the mold to dry, after Which it is placed in a suitable furnace to be baked, and annealed.

Having now described my invention and its mode of manufacture, I will proceed to set forth What I claim and desire to secure by Letters Patent of the United States.

I am aware that similar compositions of materials have been known and used previous to my use of them, and therefore irrespective
